Six Task Management Tools Compared: Permissions, Cross-Project Views, and Billing

Shusaku Yosa

タスク管理ツールの比較|チーム向け・個人向けの選び分けと主要6製品

Choose a task management tool by the work and access conditions it must support, not simply by popularity or labels such as “personal” and “developer.” This comparison covers Todoist, Notion, Trello, Asana, Backlog, and Jira. It separates capabilities checked on official pages from conditions your team should test. Features and plan information were checked on October 10, 2026; no price ranking is provided.

Write Down Personal and Team Requirements

For personal work, convenient capture and review may be enough. Team use adds questions: can another person understand ownership, deadlines, and completion criteria, and can people change the right information? The same product can support different arrangements for individuals and teams.

Count internal editors, external contributors, and read-only users separately. An agency may need access to one deliverable without seeing other clients or editing unrelated work. A small team can therefore have requirements that a free tier or default permission setting does not meet.

Condition

Fictional trial team

Why it matters

Internal editors

4 people

Update owners, dates, and states

External editors

2 people

Share only their production work and feedback

Viewer

1 person

Inspect progress without changing work

Work sample

10 production tasks across 2 projects

Test project-level and cross-project use

Retention

Comments, attachments, and decisions

Retrieve supporting records after completion

These are trial assumptions, not recommended staffing levels. Add authentication, retention, device, and contractual requirements where relevant. Define the requirement changes that would trigger reassessment rather than assuming growth always requires migration.

Compare Six Products on the Same Criteria

The table provides verified examples, not an exhaustive feature matrix. “Not checked” does not mean unsupported. Confirm that each required capability is included in the actual plan you intend to buy.

Product

Officially documented examples

Plan conditions and trial focus

Todoist

Team workspace, roles, permissions, and shared templates

Check Business and relevant plan conditions; trial external access and history

Notion

Databases, sub-items, and dependencies

Detailed permissions vary by plan; test selective sharing

Trello

Boards, multiple views, and Workspace views

Availability varies, including Premium; test two-board visibility and guests

Asana

Ownership, dependencies, Timeline/Gantt, and custom fields

Check Starter and relevant conditions; trial production-to-review handoffs

Backlog

Issues, Kanban, Gantt, and cross-project Gantt

Standard has a Gantt display-range condition; cross-project features include higher tiers

Jira

Business workflows and cross-team planning

Check Premium and relevant conditions; trial configuration and permissions

Calling Todoist or Notion personal-only, or assuming a lightweight board cannot provide cross-board views, can remove viable options prematurely. In Asana, a custom field used for budget data is also distinct from automatically reconciling accounting actuals and open commitments.

Atlassian documents Jira business projects for marketing. An engineering association does not establish that nontechnical users cannot adopt the product. Test whether the people doing the work can configure and maintain the workflow you need.

Check Free Limits and External Collaborator Billing

Free-plan suitability depends on more than headcount. Projects, views, permissions, retention, external participation, and export conditions can all matter. A trial may expose capabilities from a higher tier than the one you intend to purchase.

For the fictional four internal editors, two external editors, and one viewer, determine exactly which people are billable. Record whether an external contributor joining multiple projects changes treatment, and whether minimum seat commitments apply. Comparing a unit price without those conditions can be misleading.

Item

Check

Record

Plan

Trial tier versus intended contract

Same or different; list capability differences

Billable users

Editors, viewers, and external contributors

Count by role and billing treatment

Terms

Region, currency, tax, monthly/annual period, minimum seats

Keep comparable quotations or terms

Extras

Storage, additional capabilities, support

Included or separately contracted

Reduction and exit

Seat changes, cancellation, retention

Effective dates and export deadlines

A general cost model is billable seats multiplied by applicable rate and period, plus separately contracted additions. Adapt it where a product is not priced by seat. If region, tax, and billing period cannot be aligned, do not rank unlike figures as the cheapest option.

Trial Three Real Work Scenarios

Use the trial to complete representative work, not just inspect attractive screens. Enter the same fictional ten tasks and apply the same access and change scenarios in each product. The three working scenarios are external review, delay with reassignment, and cross-project review; export is a separate end-of-work check. Focus on mandatory conditions before testing every optional capability.

Scenario

Action

Acceptance evidence

External review

Give two external contributors only the needed assets

Unrelated projects remain hidden; useful feedback is possible

Delay and reassignment

Move T03 by one day and change its owner

Ownership, date changes, and downstream implications remain traceable

Cross-project review

List review waits across two projects

Scope and freshness are clear

Completion and export

Export tasks, comments, attachments, and history

Required fields and relationships can be retained

Record pass, conditional pass, fail, and not checked separately. A conditional pass should name the higher tier, configuration, or manual step required. Do not treat unknowns as failures or one person’s preference as evidence of team-wide adoption.

If external access fails, check the permissions, invitation method, and plan before rejecting the product. If it still cannot meet the requirement, retain reproducible evidence of the mismatch.

Inspect Exports and Migration Gaps

An export button does not establish a complete migration path. Task text may export while comments, attachments, custom fields, history, or parent relationships require different treatment. Define which records your organization needs to retain before evaluating the output.

  • Reconcile exported counts to the original sample.
  • Check owner, date, state, and parent relationships using IDs.
  • Open exported comments and attachments.
  • Inspect required archived or deleted-work records.
  • Identify fields that need conversion or manual work.

Changing tools after adoption requires preparation, but it is not automatically unrealistic. A small export test can reveal the actual gaps and work involved. Estimate conversion, preservation, and verification effort rather than assuming either a seamless move or impossible lock-in.

Test with appropriately restricted data before moving the full production set. Agree how confidential information in a trial copy will be handled when the trial ends.

Record Your Choice and Reassessment Triggers

Record the selected product and tier, evidence for mandatory requirements, remaining manual work, commercial conditions, and reassessment triggers. Check non-negotiable requirements before relying on an overall score that might conceal a critical failure.

If the team accepts a constraint such as a higher tier for cross-project views or separate attachment export, agree the owner and process too. Reassess when external participation, approval paths, or information sensitivity changes.

If you also need campaign costs and monthly plans, add them as explicit requirements. Do not assume general task tools cannot support them. Decide which system owns each field and how information will be reconciled.

Xtrategy’s Project Management brings campaign costs, task progress, workflows, and monthly plans into a project context. Start with your required fields and update responsibilities, then assess whether that arrangement fits your team.
